摘要

The invention relates to a roller polishing device and portable apparatus for surface treatment by polishing, equipped with this device The said apparatus comprises a chassis 21 fitted with a gripper system 26a; two driving shafts 22 turning on the said chassis and projecting out of the latter; a polishing device 24 which is elongated, disposable and rigidly blocked on the periphery of each driving shaft 22; a motor 31, imparting a rotational movement to each of the devices 24 and directly connected with each of the shafts 22; a driving device, efficiently connecting the said motor to the said shaft 22 in order to turn the said devices 24 in opposite directions. Each polishing device 24 has an elongated disposable cylinder 106 on which are assembled cloth discs consisting of polishing wheels 105', these discs being mutually adjacent and made integral with each other by axial compression to form an axially compressed polishing device 24. Application in particular to the polishing of aircraft bodies.
